Mike Lockwood 755fd61725 Prototype Content Provider support for MTP/PTP devices.
At this point much of the plumbing is in place, but only a few simple queries
are supported.
This is enough to support a proof of concept sample program that navigates
the file hierarchy of a digital camera connected via USB.

Also removed obsolete ptptest host test program.
